Copper catalyzed cross-coupling reactions of carboxylic acids: an expedient route to amides, 5-substituted γ-lactams and α-acyloxy esters

A convenient and recyclable catalytic protocol for the synthesis of N,N-dimethyl substituted amides, 5-substituted γ-lactams and α-acyloxy ethers from carboxylic acids using CuO nanoparticles and TBHP is described.

Sulfonic acid resin and copper salts: a novel heterogeneous catalytic system for direct hydroxylation of haloarenes

A sulfonic acid resin (INDION-770) in combination with Cu salts is demonstrated to be a versatile heterogeneous catalyst for direct hydroxylation of haloarenes to give corresponding phenols in excellent yields.

Sulfonic acid containing cation-exchanger resin “INDION-770” and copper(I) salts: a novel reusable catalyst for N-arylation of NH-heterocycles with haloarenes

Industrial grade sulfonic acid based cation-exchanger resin “INDION-770” in combination with Cu(I) salts is demonstrated to be a versatile heterogeneous catalytic system for direct N-arylation of NH-heterocycles with various haloarenes to give the corresponding N-arylheterocycles in good to excellent yields.
